FAQ​

Q: Can I use the app without logging in?​

A: Yes. All features can be used without logging in, but data is saved locally only, cannot sync across devices, and may be lost if you uninstall the app or change devices. Logging in is strongly recommended.

Q: Does sync consume a lot of data?​

A: No. Health data is mainly text and has a small data volume. Even with many records, a single sync only requires a few KB to tens of KB of data.

Q: Can multiple people use the same account?​

A: Not recommended. One account can only record health data for one person. If family members all need to use it, it is recommended that each creates a separate account.

Q: How long will data be kept on the server?​

A: As long as the account remains active, data will be kept on the server. If an account has not been logged in for 12 consecutive months, we may notify you 30 days before deletion.

Q: Can I see which servers my data is on?​

A: Our servers are located within China and comply with China's data protection regulations. Detailed server information can be found in the privacy policy.

Q: What if my account is hacked?​

A: Immediately:

  1. Change your password
  2. Check synced devices and log out of unfamiliar devices
  3. Contact customer service
  4. If you're concerned about data leakage, you can export your data and delete your account, then create a new one
